FIG. 1 illustrates an example of an implementation of an entity classification system, in accordance with one or more embodiments of the present disclosure. In some embodiments, an entity classification system 100 can include a communication bus 101, a processor 115, a system memory (RAM) 109, a read-only memory (ROM) 119, a database or storage device 103, an input device interface 121, an output device interface such as display 113, and a network communication interface 111.

In some embodiments, the communication bus 101 collectively represents system, peripheral, and/or chipset buses that communicatively connect the numerous internal devices of the entity classification system 100. The communication bus 101 may be a physical interface for interconnecting the various components, however in some embodiments, the communication bus 101 may be a network interface, router, switch, or other communication interface.

In some embodiments, the entity classification system 100 may receive and/or store multiple datasets or records, for example, datasets or records 105 and 107. Datasets or records 105 and 107 can include data values representing unclassified entities, sets of categories, and sets of subcategories associated with one or more users, or non-person entities such as commercial entities, including merchants, industrial entities, firms and businesses, governmental organizations or other suitable non-person entities. Some examples the sets of categories and the set of subcategories can be associated with, for example, standard industry classification codes, or other suitable classification system or classification scheme. The various components of the entity classification system 100 may interoperate to detect, predict, and/or infer complex patterns associated with, for example, a user or non-person entity through the classification engine 117 discussed below with respect to FIG. 2 .

In some embodiments, the entity classification system 100 may include a processor 115 configured to perform instructions provided via the bus 101 by, e.g., accessing data stored in memories 109 and 119 via the communication bus 101. In some embodiments, the Read-Only-Memory (ROM) 119 may include a non-volatile storage device, such as, e.g., a magnetic disk hard drive, a solid-state drive, flash memory, or other non-volatile memory and combinations thereof. In some embodiments, system memory 109 may include a volatile memory such as, e.g., random access memory (RAM) including dynamic RAM and/or static RAM, among other volatile memory devices and combinations thereof. In some embodiments, system memory 109 may store data resulting from processing operations, a cache or buffer of data to be used for processing operations, operation logs, among other data related to the operation of the entity classification system 100.

In some embodiments, a database or storage device 103 stores datasets or records 105 and 107 including data values associated with entities, sets of categories, sets of subcategories or other suitable data. The datasets or records 105 and 107 can include variables associated description of entities, for example, complex operations involving merchants, facilities, supplies, users or group of users associated with a non-person entity. The database or storage device 103 can be updated in real-time or near real-time when, for example, a modifying or updating event occurs related to a user, groups of users or non-person entity. In some implementations the database or storage device 103 can be part of a financial institution system, merchant system, online store system, or other suitable entity capable of registering activities associated with a user, group of users, or non-person entity once the activities are performed by a user or non-person entity, or an event affecting a user or non-person entity occurs. One or more components of the system 100 can communicate with database or storage device 103 via, e.g., the communication bus 101 to retrieve datasets or records 105 and 107 in real-time or near real-time. Accordingly, the entity classification system 100 can classify users, group of users, or non-person entities into categories and subcategories, in real-time or near real-time after one or more activities have been executed by a user, group of users, or non-person entity. In some instances, classification system 100 classify a user, group or users, or non-person entity demand, for example, in real-time of near real-time in response to a user or system request.

In some embodiments, a user or administrator may interact with the entity classification system 100 via a display 113 and a user input device interface 121. The input device interface 121 may include, e.g., a mouse, a keyboard, a touch panel of the display 113, motion tracking and/or detecting, a microphone, an imaging device such as a digital camera, among other input devices. In some implementations, results and statuses related to the entity classification system 100 and operation thereof may be displayed to the user via the display 113 or sent to another computing device not shown in FIG. 1 . Some examples of such results can include classification, categorization, and subcategorization of users, groups of users, and/or non-person entities.

As shown in FIG. 1 , communication bus 101 can also couple the entity classification system 100 to a network (e.g., network 1007 shown in FIG. 10 ) through a network communication interface 111. In this manner, the entity classification system 100 can be part of a network of computers (for example a local area network (“LAN”), a wide area network (“WAN”), or an Intranet, or a network of networks, for example the Internet. Any or all components of the entity classification system 100 can be used in conjunction with the subject technology.

FIG. 2 illustrates internal devices of a classification engine, in accordance with one or more embodiments of the present disclosure. In some embodiments, the classification engine 117 includes one or more machine learning models including a categorization machine learning model 201, and a subcategorization machine learning 203. In some embodiments, subcategories can be represented by a collection of words also referred herein as subcategory prototypes and category prototypes can be generated by combining all words belonging to the subcategories prototypes associated with a category.

In some embodiments, the categorization machine learning model 201 and subcategorization machine learning model 203 produce respectively, category prototypes represented by word embeddings and subcategorization prototypes represented by word embeddings. Word embeddings are a type of word representation that allows words with similar meaning to have a similar representation.

In some embodiments, the categorization machine learning model 201 can generate category prototypes represented by word embeddings. Such category prototypes can be used by the entity classification system 100 to assign a category to a user, group of users, or non-person entity (e.g., a merchant) based on contextual information and/or semantic meaning of words within a sentence. In some implementations, the categorization machine learning model 201 can process information related to a user, a group of users, or non-person entity to compute contextual information and/or semantic meaning utilizing a word embedding technique. Such information can include a set of words that may be meaningful or may not be meaningful (e.g. noise) to determine contextual information and/or semantic meaning associated with the user, groups of users, or non-person entity. In some implementations, the categorization machine learning model 201 can use the meaningful words within a sentence to generate multiple category prototypes represented by word embeddings.

In some embodiments, the subcategorization machine learning model 203 can generate subcategory prototypes represented by word embeddings. Such subcategory prototypes can be used by the entity classification system 100 to assign a subcategory to a user, group of users, or non-person entity (e.g., a merchant) based on contextual information and/or semantic meaning or words included in set of sentences. In some implementations, the subcategorization machine learning model 203 can process information related to a user, a group of users, or non-person entity to compute contextual information and/or semantic meaning utilizing a word embedding technique. Such information can include a set of sentences with words that may be meaningful or may not be meaningful (e.g. noise) to determine contextual information and/or semantic meaning associated with the user, groups of users, or non-person entity. In some implementations, the subcategorization machine learning model 203 can use the meaningful words within a set of sentences to generate multiple category prototypes represented by word embeddings.

In some embodiments, the categorization machine learning model 201 and subcategorization machine learning mode 203 can be implemented with a neural network. Such a neural network can be, for example, a recurrent neural network, a long short-term memory neural network, bi-directional neural network, multi time scale neural network, convolutional neural network, or other suitable type of neural network.

In some embodiments and, optionally, in combination of any embodiment described above or below, an implementation of neural network may be executed as follows:

-   i) Define neural network architecture/model, -   ii) Transfer the input data to the neural network model, -   iii) Train the model incrementally, -   iv) Determine the accuracy for a specific number of timesteps, -   v) Apply the trained model to process the newly-received input data, -   vi) Optionally and in parallel, continue to train the trained model     with a predetermined periodicity.

In some embodiments and, optionally, in combination of any embodiment described above or below, the trained neural network model may specify a neural network by at least a neural network topology, a series of activation functions, and connection weights. For example, the topology of a neural network may include a configuration of nodes of the neural network and connections between such nodes. In some embodiments and, optionally, in combination of any embodiment described above or below, the trained neural network model may also be specified to include other parameters, including but not limited to, bias values/functions and/or aggregation functions. For example, an activation function of a node may be a step function, sine function, continuous or piecewise linear function, sigmoid function, hyperbolic tangent function, or other type of mathematical function that represents a threshold at which the node is activated. In some embodiments and, optionally, in combination of any embodiment described above or below, the aggregation function may be a function that combines (e.g., sum, product, etc.) input signals to the node. In some embodiments and, optionally, in combination of any embodiment described above or below, an output of the aggregation function may be used as input to the activation function. In some embodiments and, optionally, in combination of any embodiment described above or below, the bias may be a constant value or function that may be used by the aggregation function and/or the activation function to make the node more or less likely to be activated.

FIG. 3 illustrates a block diagram of an entity classification system, in accordance with one or more embodiments of the present disclosure. In some implementations, the entity classification system 100 receives input 301. As discussed above input 301 can include words within a sentence and/or words within a set of sentences that may be relevant or may not be relevant to the classification of input 301. In some instances, the entity classification system 100 can preprocess or sanitize the information included in input 301 to extract relevant words that can be useful for the classification process. In the example shown in FIG. 3 , the entity classification system 100 can assign to the input 301 the category “Eating Places” shown at 303 utilizing category prototypes represented by word embeddings produced by the categorization machine learning 201 (discussed with reference to FIG. 2 ). Likewise, the entity classification system 100 can assign to the input 301 the subcategory “Coffee Shop” shown at 305 utilizing subcategory prototypes represented by word embeddings produced by the categorization machine learning model 201 and/or the subcategorization machine learning model 203 (discussed with reference to FIG. 2 ).

FIG. 4 illustrates a classification based on contextual information and/or semantic meaning at the sentence level, in accordance with one or more embodiments of the present disclosure. In FIG. 4 the word “delivery” can appear in input sentences 407 and input sentence 409. However, the word “delivery” as a different contextual information in each of the sentences 407 and 409. In such a case, the entity classification system 100 can determine utilizing the category prototypes represented by word embeddings (not shown in FIG. 4 ) that input sentence 407 belongs to the category of “Fast food delivery” as shown at 413. Likewise, the entity classification system 100 can determine utilizing the category prototypes represented by word embeddings (not shown in FIG. 4 ) that input sentence 409 belongs to the category “Courier delivery services” as shown at 415. In some implementations, the entity classification system 100 can assign to the sentence 407 a standard industry classification code as shown at 401. Likewise, the entity classification system can assign to the sentence 409 a different standard industry classification code as shown at 403. This is a technical advantage because otherwise a user may need to read the entire sentences to make sense what the word “delivery” means in the context of sentence 407 and 409. 100221 FIG. 5 illustrates an example of a classification based on contextual information and/or semantic meaning of multiple sentences, in accordance with one or more embodiments of the present disclosure. In some instances, the classification system 100 can determine contextual information and/or semantic meaning based on multiple included in a set of sentences identified from multiple sentences, for example, set of sentences 503. The entity classification system 100 can determine utilizing the subcategory prototypes represented by word embeddings (not shown in FIG. 5 ) that the set of input sentence 503 belongs to the subcategory of “Indian restaurant” 505 and assign such a subcategory to the multiple sentences 503. In some instances, the difference between determining a category at the sentence level as discussed with reference to FIG. 4 and determining a subcategory based on the contextual information and/or semantic meaning across multiple sentences as discussed with reference to FIG. 5 is that a subcategory has a deeper or more specific meaning. For example, the classification system 100 can assign the category of “Eating places” based on a single sentence from the set of sentences 503 and more specifically the subcategory of “Indian restaurant” 505 in real-time or near real-time. As discussed with respect to categories in FIG. 4 . The classification system 100 can assign a standard industry classification code 501 to the to the subcategory associated with the set of sentences 503 corresponding to an “Indian restaurant.”

FIG. 6 illustrates an example of a two-stage classification process performed by the classification system, in accordance with one or more embodiments of the present disclosure. In some implementations, the entity classification system 100 can extract or receive sentences or words from a data source, for instance, a search engine or other suitable data source. For instance, for a subcategory the entity classification system 100 can perform a query to retrieve results related to the subcategory description 603 from the data source. The entity classification system 100 can perform a pre-process, for example, a text scrapping process of the subcategory description as shown at 605 to sanitize the subcategory description i.e., remove not meaningful words. In some instances, the text scrapping process 605 eliminates noise from the subcategory description through, for example, a list of stop-words, then groups together inflected forms of words so they can be analysed as a single item, identified by, for example, a word lemma or in dictionary form. Thereafter, the results from the text scrapping of the subcategory description can be merged at the category level as shown at 607 to create relevant prototypes for such a category level.

In some embodiments, the entity classification system 100 can process the data at the subcategory level and/or the data at the category level through a name entity recognition process to remove generic words, for example, places, currencies, brands, geolocation, parties, or other suitable generic words. In some embodiments, the entity classification system 100 can execute a Term Frequency-Inverse Document Frequency (TFIDF) process to differentiate between different categories and different subcategories. The TFIDF process can be applied to identify how important a word is to a sentence or collection of words.

In some embodiments the data processed at 605 can be used as training data to generate a trained machine learning model, for example, a deep neural network to produce subcategory prototypes representing embeddings using, for example, a Long Short-Term Memory (LSTM), a Bidirectional Long Short-Term Memory (Bi-LSTM) or other suitable type of neural network. Such a neural network can be configured to focused on capturing contextual information and/or semantic meaning of words across multiple sentences as shown at 609 and discussed with respect to categorization machine learning model 203 in FIG. 2 . Such a neural network can produce multiple subcategory prototypes represented by word embeddings as shown at 613, 615, and 617. In some instances, the entity classification system 100 can use one or more of the subcategory prototypes represented by word embeddings to compute a subcategory for a given input, for example, input 601.

In some embodiments the data processed at 607 can be likewise used as training data to generate a trained machine learning model, for example, a deep neural network to produce category prototypes representing embeddings using, for example, a Long Short-Term Memory (LSTM), a Bidirectional Long Short-Term Memory (Bi-LSTM), or other suitable type of neural network. Such neural network can be configured to focused on capturing contextual information and/or semantic meaning across words in sentences as shown at 611 and as discussed with respect to categorization machine learning model 201 in FIG. 2 . Such a neural network can produce multiple category prototypes represented by word embeddings as shown at 619, 621, and 623. In some instances, the entity classification system 100 can use one or more of the category prototypes represented by word embeddings to output a category for a given input, for example, input 601.

In some embodiments, input 601 can include information associated with a user, group of users, or non-person entity (e.g., a merchant). In some implementations, a category and subcategory can be determined by a cosine similarity technique based on the principle of an orientation of a row vector in a n-dimensional space and the nearest vector is used to assign a category and subcategory of the input 601. Cosine similarity is a measure of similarity between two non-zero vectors of an inner product space that measures the cosine of the angle between them. In some implementations, an input vector can be produced from input 601, using already the computed word embeddings available from category/sub-category against whom it is being matched, and the cosine similarity technique can be applied between the input vector and vectors derived from the category prototypes represented by word embeddings and/or the vectors derived from the subcategory prototypes represented by word embeddings.

FIG. 7 illustrates an example of a categorization neural network implemented by the classification system, in accordance with one or more embodiments of the present disclosure. In some implementations, the categorization machine learning model 201 can be trained to produce word embeddings with a training set containing, for example, N number of words. The N number of words can be labeled with a category type and/or a subcategory type accordingly the N number of words can be used a ground truth for training purposes.

In some embodiments, each word in an Embedding Matrix (defined by weights) by a random vector can be representing by X dimensions or other suitable representation size. In some instances, every sentence passed to the neural network is assigned a sentence vector 711 using the word attention layer 709 on top of the hidden state outputs obtained from a bidirectional LSTM 707 both having a vector size of X. The vector obtained is then connected to the fully connected layer which calculates the probability that the input sentence belongs to a category and then through back propagation through time the Bi-LSTM cell weights can be updated, and likewise any random embeddings/vector that originally assigned to each word. After training, the embedding is obtained from the hidden state of Bi-LSTM, 707, and referred as dynamic embedding because based on the context of the sentence the output hidden state of LSTM can change for an inputted a word. In some instances, a fixed embedding for a word is obtained at 703 by computing arithmetic mean for all occurrences of the word in sentences of training data.

FIG. 8 illustrates an example of a subcategorization neural network implemented by the classification system, in accordance with one or more embodiments of the present disclosure. In some implementations, the subcategorization machine learning model 203 can be trained with a training set of sentences containing, for example, a maximum of N words in a sentence and a maximum of Y sentences. Such sentences can be labeled with subcategories and thus, can be used as ground truth. In some embodiments categorized sentence vectors 609 produced by the categorization machine learning model 201 can be used as a based layer including, for example, sentence 805A, 805B, and 805C. In some embodiments, after passing each sentence through this layer a sentence vector can be generated. The group of sentence vectors 805A, 805B, and 805C are representations of sequence of sentences in a document. The group of sentence vectors can be inputted to a multi stacked Bi-LSTM 807 with a deep attention network 801 to obtain the document vector 811 and again through back propagation through time the weights can be updated of each layer. It is noted that through back propagation the semantic interactions happening between words in the sentence embedding layer can be inherently captured, and the sentence embedded layer can be used every time a sentence is inputted to get a dynamic word embedding which captures semantic interactions during classification of a user, group of users, or non-person entity (e.g., a merchant) at subcategory level. Such dynamic embedding is useful for understanding of deep contextual information and/or semantic meaning when the vectors representations change with sentences. After training, the embedding is obtained from the hidden state of Bi-LSTM, 807 referred as dynamic embedding because based on the context of the sentence the output hidden state of LSTM can change for an inputted word. In some instances, a fixed embedding for a word can be obtained by computing arithmetic mean for all occurrences of the word in sentences of training data 803. While computing arithmetic mean can be further normalized by the attention score obtained from 801.

FIG. 9 is a flow chart illustrative of an example of computations executed by an entity classification system, in accordance with one or more embodiments of the present disclosure. In some embodiments, the entity classification system 100 receives or extracts for a first computing device or data source informational data associated with an entity, the informational data includes a set of sentences associated with the entity as shown at 901. Thereafter, a first machine learning model is utilized to: 1) determine a first contextual meaning among words of a sentence of the set of sentences associated with the entity based on a word embedding technique, and 2) determine at least one category associated with the entity based at least in part on the first contextual meaning as shown at 903. Thereafter, the entity classification system 100 can utilize a second machine learning model to: 1) determine a second contextual meaning shared by a subset of sentences from the set of sentences based on a word embedding technique, and 2) determine a subcategory of the category associated with the entity based at least in part on the second contextual meaning as shown at 905. Thereafter, the entity classification system 100 can generate an output indicative of the category and subcategory associated with entity to, for example, the first computing device or a second computing device as shown at 907.

It is noted that the entity classification system can achieve at least an accuracy of 98% on the classification of categories and at least an accuracy of 90% on the classification of subcategories.
